While I certainly wish that more software would reach a "done" stage, I don't think jemalloc is necessarily there yet. Unfortunately I'm aware of there being bugs in the current version of jemalloc, when run in certain environment configurations, including memory leaks. I know the folks that found it were looking to report it, but I guess that won't happen now.

Even from a quick look at the open issues, I can see https://github.com/jemalloc/jemalloc/issues/2838, and https://github.com/jemalloc/jemalloc/issues/2815 as two examples, but there's a fair number of issues still open against the repository.

So that'll leave projects like redis & valkey with some decisions to make.

1) Keep jemalloc and accept things like memory leak bugs

2) Fork and maintain their own version of jemalloc.

3) Spend time replacing it entirely.

4) Hope someone else picks it up?
